Specialist and safety glass
Safety glass is glass with additional safety features that make it less likely to break, or less likely to pose a threat when broken. Common designs include toughened glass laminated glass and wire mesh glass.
Toughened glass is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass with this method toughened glass when broken will crumble into small granular chunks instead of splintering into jagged shards. The granular chunks are less likely to cause injury.
Laminated glass holds together when shattered because, in the event of breaking, it is held in place by an interlayer,between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces.
Wire mesh glass is glass that has a thin wire, running through the glass. Primarily used as a fire stop glass
